SigmaTel has filed a lawsuit against the Korean based semiconductor company, Telechips. This lawsuit alleges that Telechips is infringing three SigmaTel patents.

The company has been successful in protecting its intellectual property in the past and continues to amass ammunition for that fight,” said Ron Edgerton, CEO and president of SigmaTel. “SigmaTel used two patents against Actions and is using three different ones against Telechips. Two of the three patents in the Telechips lawsuit issued in February 2006, and these are just the tip of the iceberg. We anticipate having up to another 100 MP3 related patents issuing over the foreseeable future. These patents will cover the semiconductor content and system architecture of MP3 players and similar devices.

Could the resignation of Actions Semiconductor’s founder, Zhao Guang Min relates to lawsuit with SigmaTel?
